LlNOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 795,028, dated July 18,1905.

Application filed November 15, 1904:. Serial N0. 232,838.

To all whom it may concern.-

Be it known that I, PHILIP T. DODGE, of Brooklyn, county of Kings, andState of New York, have invented a new and useful Improvement inLinotype-Machines, of which the following is a specification.

My invention has reference more especially to an improvement in thecommercial linotype-machine of the general organization represented inLetters Patent of the United States No. 557,000, wherein a magazinecontaining a font or set of circulating matrices is arranged in aninclined position in the main frame and adapted to be removed at will inorder that it may be replaced by another magazine containing a set orfont of matrices with characters of another size or style.

As the machines have been heretofore constructed the magazine, havin aheavy baseframe secured thereto to ho ld it in shape, could be removedonly from the rear side and by moving it, together With its base-frame,over a horizontal supporting-bar near its upper end. The elevatedposition of this bar (about five and a half feet from the floor) and theweight of the magazine were such as to demand an objectionable effortand endanger both the attendant and the magazine. It ordinarily requiresthe effort of two persons to effect the removal or insertion of themagazine at the rear, and the narrowness of the main frame, the width ofthe rear end of the magazine, and other features of construction aresuch as to prevent the removal of the magazine at the front.

The aims of the present invention are to facilitate the removal of themagazine and to reduce the cost of construction. To this end I widen theupper portion of the main frame 'in such manner as to permit the removalof the magazine from the front instead of the rear, and I provide on theforward part of the frame a roller or equivalent support to aid insustaining the magazine as it is withdrawn from the front.

I prefer to construct the magazine independently of the usual base-frameand mount a substitute for the latter permanently in place in the mainframe, so that it will serve not only as a support for the magazine whenit is in operative position, but also as a guide to assist in sustainingthe same during its removal or replacement.

I prefer to mount the escapements for controlling the discharge of thematrices in a supporting-bar distinct from the magazine and securedpermanently on the main frame, but the escapements may be carried withthe magazine as usual.

I have limited the drawings to those parts of the machine with which myinvention is immediately associated. The other parts may be of anyordinary construction and the parts herein shown may be varied indetails of form and arrangement at will, provided they have essentiallythe mode of ac tion herein described.

Figure 1 is a side elevation of the upper part of the machine having myimprovement incorporated therein, the magazine with the escapementsmountedtherein being shown in its operative position. Fig. 2 is a sideelevation of the lower front part of the frame with the magazineremoved. Fig. 3 is a side elevation similar to Fig. 1 with the magazinein operative position, the magazine in this case being shortened and theescapements mounted in the main frame. Fig. 4 is a side View of theforward end of the parts shown in Fig. 3 with the magazine removed. Fig.5 is a cross-section onthe line 5 5 of Fig. 3, looking in a downwarddirection.

Referring to the drawings, A represents portions of the main frame,which may be of any construction adapted to receive the operative parts.

B is the inclined magazine, channeled longitudinally and adapted toreceive and carry a font or set of matrices, as in the ordinaryMergenthaler machine.

D is a distributor fixed to the main frame and serving to deliver thematrices through an intermediate channeled throat or guide E into theupper end of the magazine.

F is a vertically-channeled front plate into which the matrices,released one at a time from the magazine, are delivered and throughwhich they descend to the usual mechanism by which they are assembledside by side in a common line.

G represents the escapement devices, arranged one at the lower end ofeach channel in the magazine for the purpose of releasing the matricesone at a time in the order in which their characters are to appear inprint. These escapement devices may be mounted directly in and madepermanent parts of the magazine, as shown in Fig. 1, the magazine beingsuitably lengthened to receive them, as in the commercial Mergenthalermachines of the present day, or, if preferred, the escape merits may bemounted in a channeled support H, secured rigidly to the main framebeyond the lower end of the magazine and forming a continuation of thelatter, as shown in Fig. 3.

In carrying my present invention into effect I widen the upper end ofthe main frame A, or, in other words, separate the two upright armsbetween which the upper end of the magazine is seated in such mannerthat the magazine, wider at the front than at the rear, may be drawnforward between these arms and removed from the front of the machine, acourse heretofore impossible.

*I represents a flat skeleton base-frame underlying the magazine,designed to give the same support and to prevent it from sagging orbending outof shape. Heretofore this frame has been secured permanentlyto the magazine, which was consequently increased in weight and in pricethereby. I now make this frame independent of the magazine and bolt itor otherwise secure it rigidly in place in the main frame, seating themagazine B loosely thereon, so that it may be lifted at the frolpt andwithdrawn from the machine at W1 Fig. 1 illustrates the manner in whichthe magazine carrying the escapements is sustained on this frame andremoved by lifting it at the front, drawing it forward and canting itdownward, as indicated in dotted lines. To facilitate this removal ofthe magazine, I extend the front end of the main frame upward and mounttherein a horizontal transverse roller K or similar support designed toassist in sustaining the magazine as it is moved to and fro thereover.It is obvious that the form of this support may be varied at Will,provided only it is adapted to aid in sustaining the magazine and topreventit from contacting with the channeled front plate F or otherparts which could be injured thereby.

The side-plates of the magazine (See Fig. 1) are preferably widenedvertically, as shown at b, so that in riding on the roller or support Kthey will sustain the magazine at such height as to prevent theescapements therein, G, from striking the other parts as the magazine ismoved to and from its operative position.

When the escapement mechanism is fixed on the main frame, as shown inFig. 3, these widened side plates are unnecessary, the magazine flat onits under side and sustained on the stationary frame H, as in Fig. 1,being simply lifted at its forward end and passed outward over theroller K, as indicated in dotted lines.

When the magazine without the escapements is employed, means must beprovided at the lower end for looking or holding the matrices. Irecommend for the purpose a bar thrust through the magazine from side toside between the upper and lower ears of the lowermost matrices, in themanner shown and described in a pending application of Rogers, SerialNo. 230,230.

The throat-plate E for dropping the matrices into the magazine from thedistributer is preferably hinged at e to the upper end of the fixedbase-frame H; but it may be attached to the main frame or hinged to theupper end of the magazine, as in the ordinary commercial linotype.

Having described my invention, what I claim is 1. In a linotype-machineand in combination with an inclined magazine, removable at will, a mainframe provided with means to sustain the magazine in operative position,and constructed substantially as described, to permit the removal of themagazine in the forward direction.

2. In a linotype-machine and in combination with an inclined magazine,removable at will and having its rear end of greater width than itsfront, a main frame provided with a fixed base-frame underlying andsupporting the magazine, said main frame of suitable width to permit thepassage of the magazine in a forward direction.

3. In a linotype-machine, an inclined magazine, removable at the front,in combination with a main frame, provided with fixed means forsupporting the magazine in operative position, and with means at thefront to aid in supporting the magazine during its removal orreplacement.

4. In a linotype-machine, a main frame provided with a distributingmechanism for delivering the matrices, a fixed guide-plate to receivethe matrices from the magazine, an inclined base-frame fixed in the mainframe to sustain the magazine, and a magazine removably seated upon saidbase-frame in operative relation to the distributer and the guide-plateand removable in an endwise direction at the front of the frame.

5. In a linotype-machine, a main frame,

provided with matrix receiving and distributing mechanisms and with aframe to supvsl an elevated roll or support at the front of the machineto sustain the magazine during its removal in a forward direction.

6. In a linotype-machine, an inclined magazine, removable endwise at thefront of the machine, in combination With the main frame provided With asupport for said magazine, and an escapement mechanism permanently fixedon the main frame in operative relation to the magazine.

7. In a linotype-machine, an inclined magazine removable at the front ofthe machine, in combination with a main frame provided With a rigidbase-frame to support the magazine, matrix-releasing mechanisms mountedrigidly on the main frame in operative relation to the magazine, and atransverse support above the escapements to assist in sustaining themagazine during its removal and replacement.

In testimony whereof I hereunto set my hand, this 7th day of November,1904, in the presence of two attesting Witnesses.
